Self-healing is the process of unlocking your own body’s ability to heal itself, whether on an emotional, physical, or spiritual level. Any number of techniques can be employed, including yoga, acupuncture, reiki, qigong, meditation, mindfulness practices, and more, so long as the individual is working with the goal of healing and self-actualization. The value of self-healing is that the person can tailor their healing process to their needs and comfort level. The potential downside, however, is that without expertise the journey to healing can be longer, more difficult, and less successful than it needs to be.
Your body is extremely systematic. It's compensating for everything you do. But here's the problem you're thinking way too much. You're wasting too much energy on your fears, phobias and neurosis that your body can't go into it's natural healing process.
